Our Approach to Testing 40-inch TVs

Evan Shepard/Gadget Review

We’ve redefined TV buying guides, setting us apart from any other site on the planet. Our unique approach combines in-house verification with a comprehensive dataset from trusted sites, focusing on key testing metrics like brightness (SDR and HDR), EOTF, response time, contrast ratio and color gamut.

We collect this data so you don’t have to, simple as that. We then average that testing data to represent that product’s capabilities accurately. Subsequently, we then leverage that data, filter and sort our buying guides, ensuring that all the products on our guides meet the strict requirements for your use case, such as ensuring smooth gaming experiences with fast response times and vibrant visuals tailored for gaming immersion.

You may notice some of our graphs contain “Source: RTings”. This is to indicate that the data we’re showing off in a graph has come from a single source – because it’s the only source that actually tested the criteria and had data for it! Normally, our data is an average out of all of the various publications that test and provide data to give you a good idea of how a product is going to perform on average.

Which Criteria Matters for Testing 40 Inch TVs?

By focusing on these criteria (3 required, 4 nice to have), anyone can quickly and easily compare these TVs and how they’ll perform. This helps you make an informed decision and purchase a TV that will fit into your small or tight space.

Below, you’ll find a detailed list of every TV review website we’ve identified, organized by their respective Trust Ratings from highest to lowest. But we didn’t stop there. We’ve meticulously reviewed each publication and verified the data by checking whether the authors have bio links to MuckRack or LinkedIn. We’re committed to not only checking the facts but ensuring their veracity.

Best 40 Inch TV’s Test Data & Results

1. SDR & HDR Brightness TV Test Results

In well-lit rooms, the brightness level of your 40-inch TV, quantified in nits, is key to a great viewing experience. A TV that doesn’t meet the brightness requirement will struggle against natural and artificial light, resulting in a dim, lackluster image. Essentially, nits measure how well your TV can stand up to light interference, with higher values ensuring a sharper, more vivid display.

For standard viewing on the best 40-inch TV, you should look for at least 300 nits to strike the right balance between clarity and color quality in standard dynamic range (SDR) content. For high dynamic range (HDR) content, which offers richer colors and greater contrast, a minimum of 700 nits is ideal to truly appreciate the enhanced visuals. These brightness levels are recommended to ensure your TV performs well in bright settings, allowing you to enjoy your shows and movies without any loss in detail or quality. Aim for these minimums: SDR Brightness >= 300 nits; HDR Brightness >= 700 nits for the optimal experience.

Discover the top 40-inch TVs, ranked from brightest to least, all exceeding our brightness criteria.

SDR Brightness (in nits, higher is better)

HDR Brightness (in nits, higher is better)

2. Color Gamut (DCI P3 xy) TV Test Results

Color gamut defines the range of colors a TV can reproduce, directly affecting how vibrant and true-to-life the images look. A wide color gamut in a 40-inch TV brings out richer, more vivid colors – from the lush greens of a garden to the bright colors of animated characters, enhancing your viewing experience to closely mimic real life.

This concept is technically measured against standards like the DCI P3 xy, a benchmark for high-quality visuals. A 40-inch TV covering a higher percentage of this color space can display colors more accurately and vividly.

For those who prioritize vibrant and immersive visuals in a smaller package, aiming for a 40-inch TV with a color gamut of 90% or higher on the DCI P3 xy scale is ideal. This ensures that the content you watch is as vibrant and lifelike as possible, bringing a big viewing experience to a smaller screen. Below is all the TVs on this guide sorted by best to least in Color Gamut.

Below are the top 40-inch TVs, ordered by color gamut, all exceeding our testing criteria.

DCI P3 XY Color Gamut (as a %; high is better)

3. EOTF Test Results

The Electro-Optical Transfer Function (EOTF) plays a critical role in ensuring the content on your TV looks exactly as the creator intended. This technical feature adjusts your screen’s brightness levels, ensuring every scene, from the darkest shadows to the brightest highlights, is displayed with true-to-life accuracy.

In rooms flooded with light, a TV that nails EOTF calibration shines by preserving the intended contrast and detail in the picture despite the challenging conditions. It balances the brightness so that images remain vibrant and full of detail, unaffected by the glare of ambient light.

A TV that excels in managing EOTF offers an immersive and authentic viewing experience. It brings creators’ visions to life, accurately rendering every scene with the proper light and dark levels, no matter the lighting in your room. This means you get a consistent, realistic picture that captures the full spectrum of colors and contrasts, from the subtlest hues to the most intense explosions. Below is all the TVs on this guide sorted from best to worst in EOTF.

Below are all the 40-inch TVs on our list, ordered by EOTF, all exceeding our minimum requirement.

EOTF (source: rtings.com – 0 = no data exists; lower is better)

4. Response Time TV Test Results

A slow response time on a 40-inch TV during fast-paced scenes is like trying to watch a thrilling movie with a foggy lens. Imagine settling in for an action-packed sequence, only to have the swift movements turn into a blur, robbing you of the crisp, clear detail you crave. This isn’t just a minor annoyance; it’s a major detriment to your viewing experience, leaving you with a picture marred by motion blur and visual artifacts.

So, what exactly is response time? It measures how quickly a pixel on your TV can change from one color to another. In the context of watching fast-moving content or enjoying dynamic scenes on a TV, a low response time is crucial. A response time of 15 ms or lower is good, but if you plan on gaming on this set, aim for a response time of 10 ms or lower. At these levels, your 40-inch TV ensures smooth transitions and sharp visuals, making every scene come to life without any distracting blurs or delays.

Below are the top small TVs, ordered by response time.

Response Time (in milliseconds; lower is better)

5. Contrast Ratio Test Results

For TV enthusiasts, a solid contrast ratio is crucial for enjoying your favorite TV shows or movies, especially in darker settings. This feature directly impacts how lifelike and dynamic the picture appears on your screen, ensuring that dark scenes are displayed with clear, crisp blacks instead of murky grays and bright scenes retain their detail without appearing washed out.

Put simply, the contrast ratio is all about the range of luminance a TV can produce, from the deepest blacks to the brightest whites. It’s what brings depth to the image, enhancing the realism of every scene. Watching a movie in the dark, for example, the difference between a TV with a poor contrast ratio and one with a high ratio is stark: the former struggles, blending shadows into a flat gray, while the latter delivers true black, making night scenes more immersive and detailed.

Ideally, a contrast ratio of 10,000:1 is what you should aim for in a 40-inch TV. This level of luminance variance ensures that you’re getting a picture quality that can handle the nuances of lighting in any scene, providing a viewing experience that’s both rich and engaging. Note: OLED TVs have infinite contrast ratio, indicated by “0.”

Below are the top 40-inch TVs, ordered by contrast ratio, all exceeding our testing criteria.

Contrast Ratio (higher is better)

40 Inch TVs: Mistakes To Avoid

  1. Neglecting Viewing Distance: Viewing distance is critical for comfortable viewing, especially with smaller TVs like the top 32-inch TVs or 40-inch models. Ensuring an appropriate viewing distance for your TV’s size prevents eye strain and enhances the overall viewing experience. The same applies to larger screens; ensuring the ideal viewing distance for the best 50-inch TV is essential to achieve a balance between screen size and viewer comfort, enhancing immersion in the content you’re viewing.

  2. Overlooking Compatibility: Checking compatibility with existing devices is essential to avoid connectivity issues. A 40-inch TV ensures seamless integration with gaming consoles, streaming devices, and sound systems, which is crucial for uninterrupted entertainment. For gamers, check out our guide to the best gaming TVs. And if you’ve already bought a soundbar, read our guide on how to connect a soundbar to your TV.

  3. Ignoring Lighting Conditions: Considering room lighting conditions is key to optimizing picture quality. Adequate brightness and anti-glare features are particularly important for 40-inch TVs placed in areas with varying light conditions, like living rooms or bedrooms. Lighting consideration is equally important for curved TVs, as their unique shape can reflect light differently, affecting the viewing experience in well-lit rooms.

  4. Fixating Solely on Screen Size: While screen size is important, focusing only on it overlooks other crucial features. With 40-inch TVs, considering factors like resolution, refresh rate, and smart TV capabilities ensures a well-rounded entertainment experience tailored to your needs.
